268 On a new Genus of Scatopsid Flies. 
apically (no pulvilli). Upper branch of the radial sector less 
transverse. Costa extending well beyond the tip of Fy4,>5. 
Bases of the lower branch of the media and of the anal vein 
defective. Cross-vein connecting 2s with Cu meeting Cu 
before the fork. Wing-membrane with numerous short 
macrotrichia, 
Genotype: C. antennata, sp. n. 
The flies are considerably larger than any European 
Scatopsid, and have some superficial resemblance to Myceto- 
philide of the genus Leiomyia. Corynoscelis, on the other 
hand, resembles the other HKuropean Scatopsida in size and 
appearance, 
Canthyloscelis antennata, sp. n. 
Autenne black. Eyes in punctiform contact above the 
antenne in the ¢, just separate in the 2. Thorax with 
three rather distinct dark dorsal stripes, on a brownish- 
ochreous ground. Male claspers rather large, pointed, the 
basal half broad; ninth tergite with two sharp points. Hind 
femora pale yellowish on the basal half, including the com- 
mencement of the swollen portion ; apical half brown, darker 
at the tip and at the junction with the pale portion. Hind 
tibia brown, with a more or less conspicuous yellowish ring 
occupying the middle third. First hind tarsal joint nearly 
cylindrical, about half as long again as the second. Coxe 
all ochreous. Wings with a conspicuous dark band near the 
tip, somewhat crescent-shaped, with the convexity inwards. 
Wing-length 5-6 mm.

type and two other ¢ from Wainuiomata, also two ¢, two @ 
without exact data, in the British Museum ; another ? in the 
Cambridge Museum, 
Canthyloscelis claripennis, sp. n. 
Antenne brownish on the basal half or more, black apically. 
Kyes of $ separated by about the width of two ommatidia., 
Thorax indistinctly striped. Male claspers smaller than in 
C. antennata, rounded apically ; ninth tergite simple. Hind 
femora with the dark colour more extensive, the pale yellow 
confined to the slender basal portion. Hind tibize without a 
distinct pale ring in the middle. First hind tarsal joint 
nearly cylindrical, about half as long again as the second.
